Abstract
The present invention relates to a kind of anti-compaction compound fertilizers and preparation method thereof.A kind of compound fertilizer, according to parts by weight, including following components: 8 parts~70 parts of acicular crystal urea；1 part~10 parts of magnesium sulfate；0.5 part~2 parts of citric acid；10 parts~50 parts of phosphorus source；10 parts~70 parts of potassium resource；And 1 part~5 parts of microelement.Above-mentioned compound fertilizer can anti-compaction.
Description
Technical field
The present invention relates to a kind of anti-compaction compound fertilizers and preparation method thereof.
Background technique
The Integration of Water into Fertilizer is will to irrigate the new agricultural technology to combine together with fertilising, is to irrigate and apply fertilizer to organically combine
Best way.It is calculated according to 900,000,000 mu of irrigated areas of China, water-fertilizer integral application percentage only has 2.87% at present, therefore sends out
Exhibition has a extensive future.It is very universal using one body technique of liquid manure in the agriculture developed country such as Israel, U.S., mainly select liquid
Body fertilizer or rapidly dissolvable powdery multi-element fertilizer.But liquid fertilizer needs the ducts to extend in all direction, and needs
Long term distance transport, in contrast, the flexible rapidly dissolvable powdery multi-element fertilizer of traffic condition just more have obvious
Advantage.
However, the powders fertilizer such as sulphur ammonium, phosphorus ammonium, ammonium nitrate, urea, hydrophily is big, in storage and transport all there may be
Agglomeration.Caused by because of the hydrophily of this moisture absorption or agglomeration system by fertilizer oneself, it is difficult for entirely preventing the generation of this phenomenon
's.In the past, in order to eliminate the primary of agglomeration on condition that preventing the moisture absorption, the method for use is the chemical fertilizer blending that hygroscopicity is low
Into bibulous fertilizer, mixed fertilizer or chemical conversion fertilizer is made, perhaps powdered fertilizer is granulated or non-hygroscopic
Property powdery stable material (such as diatomite, kaolin, talcum etc) be adhered to granulated fertilizer surface, or packaging is held
No matter device reform is also impossible to entirely prevent the moisture absorption, agglomeration using what kind of method at completely moisture-proof container.
Summary of the invention
Based on this, it is necessary to provide it is a kind of can effectively anti-compaction a kind of anti-compaction compound fertilizer and preparation method thereof.
A kind of compound fertilizer, according to parts by weight, including following components: 8 parts~70 parts of acicular crystal urea；1 part of magnesium sulfate
~10 parts；0.5 part~2 parts of citric acid；10 parts~50 parts of phosphorus source；10 parts~70 parts of potassium resource；And 1 part~5 parts of microelement.
In above-mentioned compound fertilizer, by needle-shaped urea reduce its recrystallization between multielement powder fertilizer other components,
Anhydrous magnesium sulfate promotes the critical relative moisture of powder fertilizer, citric acid stable crystal form, and the contact point of particle is avoided to repeated
Moisture absorption, dissolution, recrystallization achieve the purpose that prevent fertilizer hardened；Produce it is simple and easy, do not need addition it is water-soluble, fat-soluble,
Hydrophobic anti hardening agent, complete water-soluble no slag, later period can also carry out vacuumizing packaging, be a kind of ideal accurate filling
Irrigate facility fertilizer.
Specific embodiment
Further details of theory is made to a kind of anti-compaction compound fertilizer and preparation method thereof mainly in combination with specific embodiment below
It is bright.
